None needed.  The posting is bang on topic.

The term "auto indentation" covers several aspects in CC Mode.
(i) There's the indentation which happens when you type <TAB> or C-j.
(ii) There's the "electric indentation" which happens when you type a
semicolon or parenthesis or ....

In the current versions of CC Mode (5.28 or 5.30.n:  use M-x c-version to
see which one you've got), there isn't much control you can exercise over
these.  In the soon-to-be-released CC Mode 5.31, you can independently
disable the "electric indentation".

`c-indent-line' doesn't exist.  `indent-tabs-mode' merely says whether
you want to use (mainly) tabs to indent with or only spaces.

Try (setq c-syntactic-indentation nil).  If you still want to be able to
indent with <TAB> or C-j, wait for CC Mode 5.31, which will be available
on <http://www.sourceforge.net/release.php> some time "soon".
